The government watchdog group Judicial Watch cites sources in the government warning that ISIS will attack the United States along the Mexican border.

According to high level sources, ISIS terrorist are operating in Ciudad Juarez on the border across from the city of El Paso, Texas.

The sources state ISIS operatives will use vehicle born improvised explosive devices in the attacks. Homeland Security, Justice and Defense Department agents have been placed on high alert “and instructed to aggressively work all possible leads and sources concerning this imminent terrorist threat,” Judicial Watch reports.

The attack is “coming very soon” the high-level source warned. It is speculated an attack will happen on the anniversary of the September 11, 2001 terror attacks.

“An attack is so imminent that the commanding general at Ft. Bliss, the U.S. Army post in El Paso, is being briefed, another source confirms. The Department of Homeland Security (DHS) did not respond to multiple inquiries from Judicial Watch, both telephonic and in writing, about this information,” reports Judicial Watch.

Last week a former CIA covert operations officer, Mike Baker, said on the Laura Ingraham Show he believes there is “a lot of communication” between ISIS and Mexican drug cartels.

“We've had good intel over the years about al Qaeda, about their efforts to coordinate with, as an example, Mexican cartels… in an effort to try to exploit our southern border,” he said. He added that ISIS is well aware of the lack of security on the border and may take advantage of it.

"The drug cartels use the same operational plan as terrorist groups do… They kill their opponents, they behead their opponents, they brag about it and they have operational control of many portions of the southern border of the United States. They're vicious as some of these other terrorist organizations,” Poe told Newsmax TV.
